Handle construction



1968 J. P. GRENE ETAL KEWSQfi HANDLE CONSTRUCT ION M m s United States Patent 3,397,926 HANDLE CONSTRUCTION John P. Greene, Mountain Lakes, N.J., and Willis Lee Stewart, Sutfern, N.Y., assignors to H & G Industries, Inc., a corporation of New York Filed Jan. 4, 1965, Ser. No. 422,994 1 Claim. (Cl. 30630) ABSTRACT OF THE DISCLOSURE A handle has an elongated cylindrical bore extending thereinto from one end, an externally threaded sleeve in the bore and cement in said bore surrounding said sleeve throughout its length, the inner end portion of the sleeve being cylindrical and extending beyond the threads providing for the holding of the sleeve against both longitudinal movement and rotation in the bore.

This invention relates to handle construction and particularly to handle construction which facilitates the application of an extension handle thereto.

The invention has for its salient object to provide simple, practical and inexpensive means for connecting a handle extension to a handle and to a method of assembling the structure therefor.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application and in which:

FIGURE 1 is a front elevational view of a handle construction embodying the invention associated with a support rod of a paint roller;

FIGURE 2 is a greatly enlarged central longitudinal sectional view through one end of the handle with the support rod shown in the side elevation;

FIGURE 3 is a similarly enlarged central longitudinal sectional view of the other end of the handle;

FIGURE 4 is a horizontal sectional view on the plane of the line 44 of FIGURE 2; and

FIGURE 5 is a horizontal sectional view on the plane of the line 5-5 of FIGURE 3.

In FIG. 1 there is shown a handle .10 having at one end thereof a rod 11 to which is connected a paint roller 12;

In FIG. 2 there is shown in section the end of the handle connected to the rod 11 and it will be noted that the handle has an inwardly extending bore, preferably cylindrical, the bore being shown at 13.

The end of the rod 11 is swaged to provide outwardly extending fins 15 and it will be noted that the portion 16 of the rod 11 is rectangular in shape and has the corners of the rectangle rounded as shown at 17.

Before the swaged end of the rod is forced into the bore 13, the bore has inserted therein suitable cement as shown at 18 and 19. The rod is then forced into the bore and the fins 15 out into the wall of the bore.

3,397,926 Patented Aug. 20, 1968 ice The other end of the handle shown in FIG. 3 has an inwardly extending cylindrical bore 20 into which is inserted suitable cement such as an epoxy adhesive shown at 21. A corrugated sleeve 22 having a closed end 23 is forced into the cement and the bore 20 and the cement surrounds the closed end 23 and the corrugations in the wall of the sleeve. The sleeve is preferably thin-walled and so corrugated as to form rolled screw threads 24 to receive a correspondingly threaded end of an extension rod 26, the threads terminating short of the closed end 23 to leave a plain cylindrical portion 25. It will be seen from the showing in FIG. 3 that the layer of cement between the wall of the bore 20 and the outer corrugated surface of the sleeve 20 firmly secures the sleeve in position in the bore 20, and the cylindrical portion 25 prevents the sleeve from being unscrewed from the cement.

A metal ferrule 27 is preferably secured to the outer end of the wooden handle 10 to reenforce the handle against splitting.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claim.

1. A handle having an elongated cylindrical bore extending thereinto from one end, a thin-walled cylindrical sleeve in said bore having a closed inner end and having its circumference along a portion of its axial length defined by rolled screw threads extending from one end and terminating short of said closed end, the remaining portion of its axial length between said screw threaded portion and said closed end having a uniform outer diameter at least equal to the outermost diameter of said threads and of a length greater than the pitch of said threads, and cement in said bore surrounding the length of said sleeve, whereby the sleeve is held against both longitudinal movement and rotation.
